I'm generating the bitmap of a view to show it as a marker on the Map. It is working fine but the issue that i'm facing is that elevation of the view is not showing.
private Bitmap getMarkerBitmapFromView(View view) {
view.measure(View.MeasureSpec.UNSPECIFIED, View.MeasureSpec.UNSPECIFIED);
view.layout(0, 0, view.getMeasuredWidth(), view.getMeasuredHeight());
//view.buildDrawingCache();
view.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
Bitmap returnedBitmap = Bitmap.createBitmap(view.getMeasuredWidth(), view.getMeasuredHeight(),
Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(returnedBitmap);
/*canvas.drawColor(Color.WHITE, PorterDuff.Mode.SRC_IN);
Drawable drawable = view.getBackground();
if (drawable != null)
drawable.draw(canvas);
*/
view.draw(canvas);
return returnedBitmap;
}
public static Bitmap generateBitmap(Context context, String msg) {
Bitmap bitmap = null;
LayoutInflater mInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
//Inflate the layout into a view and configure it the way you like
RelativeLayout view = new RelativeLayout(context);
try {
mInflater.inflate(R.layout.point_helper, view, true);
} catch (Exception e) {
e.printStackTrace();
}
TextView tv = (TextView) view.findViewById(R.id.textView);
tv.setText(msg);
//Provide it with a layout params. It should necessarily be wrapping the
//content as we not really going to have a parent for it.
view.setLayoutParams(new ViewGroup.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT));
//Pre-measure the view so that height and width don't remain null.
view.measure(View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED),
View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED));
//Assign a size and position to the view and all of its descendants
view.layout(0, 0, view.getMeasuredWidth(), view.getMeasuredHeight());
//Create the bitmap
bitmap = Bitmap.createBitmap(view.getMeasuredWidth(), view.getMeasuredHeight(), Bitmap.Config.ARGB_8888);
//Create a canvas with the specified bitmap to draw into
Canvas c = new Canvas(bitmap);
//Render this view (and all of its children) to the given Canvas
view.draw(c);
return bitmap;
}
Drawable for layout background, put it inside drawable folder and set it.
bg.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<layer-list>
<item>
<shape>
<solid android:color="#35000000" />
<corners android:radius="2dp" />
</shape>
</item>
<item android:bottom="3dp" android:left="1dp" android:right="3dp" android:top="1dp">
<shape>
<solid android:color="#ffffff" />
<corners android:radius="1dp" />
</shape>
</item>
</layer-list>
</item>
</selector>
I slightly modified your logic, Have a look at this code. It requires a layout. If layout is not possible to provide, try to give the parent view of the bitmap view.
